In terms of the finite-element method, we analyse the thermal stress distribution in a layered material with two layers of Ceramic-metal direct bonding Material(non-FGM) and in FGM during their fabrication process. Thermal stresses are computed as the materials are cooled from a joint fabrication temperature of 1200 K to 300K. We obtain the relationships between the thermal stress and compositional gradient exponent, P and graded thickness, t for Ceramic-Metal FGM. In this study, it is expected that the optimal value of P is obtained 1 and as the graded thickness is increased to larger values, the Residual Stresses continue to decrease.
